|  | Boom State 
 
  In the 1960s the Western Australian economy experienced a boom due to a massive increase in the types and volume of minerals being mined. Since 1890 gold had been the leading resource mined and exported from the State, but the discovery of huge new deposits of coal, iron ore, nickel, alumina, mineral sands and oil and gas  in the 1950s and 1960s led to the development of new mining ventures. Export of iron ore began in 1966, the same year nickel was discovered at Kambalda, while the mining of mineral sands (1957), bauxite (1964) and oil (1966) all commenced in this period. 
 As a result of the mining boom, Western Australia's position within the 
      Commonwealth changed. The rapid development and exploitation of its mineral 
      resources during the 1970s transformed Western Australia from a recipient 
      State dependent on Commonwealth grants financing government programs into 
      one of the wealthiest States in the Commonwealth. By the turn of the century 
      Western Australia contributed 28% of the nation's export earnings through 
      its mining and farming industries.
 
 
 With the turnaround in Western Australia's financial fortunes, secessionist 
      feelings of resentment towards the federal government did not change. Complaints 
      about Western Australia's position now focussed on the Commonwealth taking 
      more than its fair share of the wealth of Western Australia.
